NAME

App::Rad::Help - 'help' command extension for App::Rad

VERSION

Version 0.02

SYNOPSIS

you can add inline help for your App::Rad commands via "$c->register()" or "$c->register_commands()":

    use App::Rad;
    App::Rad->run();
    
    sub setup {
        my $c = shift;
        
        $c->register_commands( {
                foo => 'expand your foo!',
                bar => 'have a drink! arguments: --drink=DRINK',
            });
            
        $c->register('baz', \&baz, 'do your thing');
    }

you can also do it with the attribute 'Help' in your subs

    sub my_command :Help(this is my command) {
        ...
    }
    
    sub another_cmd
    :Help(yet another command)
    {
        ...
    }
